Frequently Asked Questions of Youth Helmet
Skip the age guess — measure instead. Wrap a soft tape measure around your child's head, about 2.5 cm above the eyebrows. That number in centimetres is the only size that matters. Most kids aged 5–8 measure 50–54 cm; ages 8–12 usually land at 52–56 cm. Two kids the same age can easily be two sizes apart, so always measure first, then match to the chart.
Yes, everywhere, every time. Australian Road Rules (Rule 256) require all cyclists — any age, any surface — to wear an approved helmet, fastened securely. That covers roads, shared paths, footpaths, bike tracks, and car parks in every state and territory. There are narrow exemptions for medical conditions and certain religious headwear, but for most kids it is simply the law. Fines vary by state and can exceed $400.
Yes. The Consumer Goods (Bicycle Helmets) Safety Standard 2024, updated by the ACCC on 22 March 2024 — is Australia's mandatory requirement. Every helmet must comply with one of six recognised standards; the most common is AS/NZS 2063:2020. Look for the certification label inside the helmet before you buy. Every helmet in this collection is fully compliant. Details are on the ACCC Product Safety website.
For trail riding and bike parks, yes. MIPS is a thin slip-plane layer inside the helmet. During an angled impact, the most common type in mountain biking, it allows the outer shell to rotate slightly, reducing rotational force on the brain. A 2022 study in Scientific Reports found MIPS helmets produced measurably lower peak rotational acceleration than standard helmets in oblique testing. It is not a legal requirement. For casual riding on flat ground, a well-fitted standard helmet is fine. For anything involving jumps, roots, or drops, MIPS is worth it.
You send it back. Every helmet is covered by our 30-Day Perfect Fit Guarantee — if the size is wrong, or your child simply will not wear it, return it within 30 days for an exchange or a refund. We built that policy specifically because helmet sizing is the one thing parents cannot fully judge online. Order the size your measurement points to, and if it is out by a centimetre, we will sort it.
Yes, and it is usually the faster option. Contact us with your order number and the size you need and we will arrange the swap. Most size exchanges are one letter up or down, and because we stock the full range in each model, there is rarely a wait. Keep the helmet unworn outdoors and with its tags on until you have completed the fit test at home.
Depends on the model, and the product page will tell you. Standard bicycle helmets are certified for cycling and wheeled recreational use. The dual-certified Triple Eight models in this collection carry both bicycle and skate certification, which means they are tested for the multiple lower-speed impacts typical of skate parks as well as the single hard impact a bike helmet is designed for. If your child splits their time across a bike, a scooter and a skateboard, a dual-certified helmet is the one to buy — you are buying one helmet instead of two.

Why Choose Our Quality Products For Your Child?
How to choose the Right Youth Bike Helmet: Age, Fit, and Riding Style
The single biggest mistake parents make is buying by age instead of head circumference. Head sizes vary enormously between children of the same age, a 6-year-old and an 8-year-old can have identical measurements, or be several centimetres apart. Always measure first.
How to measure your child’s head at home:
- Use a soft tape measure (or a piece of string measured against a ruler)
- Wrap it around the widest part of the head — roughly 2.5 cm above the eyebrows, level with the ears
- Record the circumference in centimetres
- Match to the size chart below
The two-finger fit test: Once the helmet is on, slide two fingers between the front rim and your child’s eyebrows. One to two fingers’ width is correct. The helmet should sit level, not tilted back or forward. Chin straps should form a V just under each ear, with only one finger fitting between strap and chin.
Kids aged 5–8: what to prioritise
For younger riders, weight and fit simplicity matter most. A heavy helmet tips forward on a small head, restricts vision, and guarantees complaints. Look for helmets in the 50–54 cm range with a rear dial-fit system — these let you adjust as your child grows without buying a replacement every season. Opt for 10 or more vents; kids overheat quickly and a hot helmet gets taken off.
Youth bike helmet size chart: age to head circumference
Age is a starting point, not a size. Measure first, then match the number below. If your child falls between two sizes, size up and use the rear dial to tighten, a helmet they grow into beats one they grow out of in four months.
Yet to confirm by client when information is finalized
| Age guide | Head circumference | Helmet size | Best fit from our range |
| 2–5 yrs | 45–50cm | XXS / XS | Toddler Helmets Ages 2-5yrs |
| 5–6 yrs | 50–53cm | XS / S | Youth range (this collection) |
| 7–8 yrs | 52–55cm | S / M | Youth range (this collection) |
| 9–12 yrs | 54–57cm | M / L | Teen Helmets Ages 9yrs+ |
Manufacturer sizing varies. Triple Eight, Hornit and Globber each cut their shells slightly differently, so always check the size shown on the individual product page against your measurement rather than relying on the size letter alone. Every product listing on this page shows its exact centimetre range.

Youth MTB helmets: what changes on the trail
A road or footpath helmet and a mountain bike helmet are built to the same certification but shaped for different crashes. If your child is riding singletrack, pump tracks or bike park, three things change.
Extended rear coverage. MTB helmets drop lower at the back of the skull, because trail falls are more often backwards and sideways than the forward pitch you get on a footpath.
A visor. Not cosmetic — it deflects low branches and keeps sun out of a rider’s eyes on a descent where they cannot take a hand off the bars.
Rotational impact protection. Most trail impacts land at an angle rather than square on. MIPS and similar slip-plane systems reduce the rotational force transferred to the brain in those angled hits.
For light trail use, a well-fitted dual-certified helmet handles the job, our multi-sport helmets carry both bicycle and skate certification and take repeated low-speed impacts better than a single-certified shell. For genuine mountain biking with jumps, drops and roots, look for a purpose-built MTB helmet with extended coverage and a visor.
Australian helmet safety standards: what the certification label actually means
Wearing a helmet is not optional in Australia. Under Australian Road Rules (Rule 256), every cyclist, regardless of age, must wear an approved helmet, securely fitted and fastened, at all times while riding. This applies in every state and territory, on roads, bike paths, shared paths, footpaths, and car parks. Fines range from $116 in some states to over $400 in others.
The governing standard is the Consumer Goods (Bicycle Helmets) Safety Standard 2024, updated by the ACCC on 22 March 2024. Under this standard, a helmet must comply with one of six recognised international standards, the most common being:
- AS/NZS 2063:2020 — Australian/New Zealand standard for bicycles and wheeled recreational devices
- EN 1078:2012+A1:2012 — European standard for pedal cyclists
- US CPSC 16 C.F.R. Part 1203 — US Consumer Product Safety Commission standard
Every helmet in this collection carries at least one of these certifications. Check the label inside the helmet, compliant helmets will display the relevant standard code. If there’s no label, don’t buy it.
What AS/NZS 2063:2020 tests for:
- Impact energy absorption (EPS foam performance)
- Retention system strength (chin strap and buckle)
- Field of vision (minimum peripheral coverage)
- Helmet coverage area (minimum area of the head protected)
- Penetration resistance
Certification is the floor, not the ceiling. A helmet that barely passes still passes. Higher-quality helmets from established brands — Bell, Giro, Fox, Nutcase, Smith — typically exceed the minimums, particularly on retention system ergonomics and EPS liner density.
How long does a youth bike helmet last?
Replace your child’s helmet every five years, or immediately after any significant impact — even if there is no visible damage.
The EPS (expanded polystyrene) foam liner is a single-use impact material. It compresses permanently on impact and does not recover. A helmet that has taken a hard fall may appear intact but offer substantially reduced protection. Victoria’s Department of Transport recommends replacement every five years due to gradual foam degradation from UV exposure, sweat, and general use.
Visual inspection checklist — replace if you find:
- Any crack in the outer shell, however small
- Dents or deformations in the EPS foam liner
- A retention system (dial or strap) that no longer adjusts securely
- Any helmet over five years old, regardless of condition
- Any helmet involved in a crash with impact, regardless of appearance
If you are unsure whether a helmet needs replacing, the answer is always to replace it. The cost of a new helmet is low. The cost of relying on a compromised one is not.
For more on helmet safety for children and young riders, the Better Health Channel (Victoria’s government health resource) provides evidence-based guidance on fitting, wearing, and caring for children’s bicycle helmets.
Youth Helmet Fit, Care, and Storage: Making Protection Last
A certified helmet that is stored badly or fitted incorrectly provides less real-world protection than its test results suggest. These are the practical steps that matter.
Fitting checklist:
- Place the helmet level on the head, front rim two fingers above the eyebrows
- Adjust the rear dial so the helmet is snug but not painful
- Fasten the chin strap — straps should form a Y shape just below each ear
- Check: one finger fits between chin and strap; the helmet does not rock when you push it
- Ask your child to shake their head — the helmet should not shift
Storage and care:
- Store helmets away from direct sunlight — UV degrades EPS foam over time
- Do not store in car boots; prolonged heat exposure weakens foam structure
- Clean with mild soap and warm water only — solvents and alcohol damage the shell and foam
- Never paint or apply stickers over ventilation channels
- Check the dial-fit mechanism and chin buckle every few months for wear
